THERMAL OVERLOAD RELAY - TZ
TERMIČKA ZAŠTITA
Prevents overheating of motor windings. Can be used with motors that have built-in temperature-dependent resistors (PTC) in windings. Choice of automatic or manual reset.
Basic features:
-standard supply voltage: 230Vac; 24Vac/dc
-consumption: 2VA
-cut off  threshold: when the PTC resistance reaches 3000ohm  (+ / -10%)
-restart: when resistance drops to 2000ohm (+ / -10%)
-contact rating: 5A/220Vac
-operating temperature range: -10 / +55 C


 TERMIČKA ZAŠTITA MOTORA
LEVEL SWITCH - RZP
ZAŠTITA PUMPE OD RADA NA SUVO

It is used to detect the presence of conductive liquids in metal or tanks of insulating material. It can be used to automatically refill the reservoir or to protect the pump from dry running. With jumper 5-6 on the front panel you can choose whether the relay will be on when the liquid level reaches the probe S1 (pump protection) or to be off when S1 is reached (filling a tank).
Basic features:
power supply: 230Vac
consumption: 2VA
contact rating: 5A/230Vac
mounting: rail 35mm
